   Concerning...Tornado Watch 134...

   The severe weather threat for Tornado Watch 134 continues.

   SUMMARY...A couple of storms may develop across north Texas this
   afternoon and evening. All severe threats will be possible with any
   storms that develop.

   DISCUSSION...22z observations and surface analysis show a few deeper
   updrafts beginning to coalesce along and ahead of a bulging dryline
   near the DFW metroplex. Storms have struggled to mature thus far,
   which suggests that some MLCINH remains across the area, and this is
   also supported by the modified 19z FWD observed sounding. Upper
   level lift from the shortwave trough moving through the southern
   Plains will likely continue to erode the remaining inhibition and
   could support the development of a few storms. The environment
   downstream is moist and unstable with dewpoints around 70 F and
   upper level wind profiles favor a discrete supercell mode with
   effective shear of 60-70 kt. All severe threats will be possible
   with any storms that are able to develop. A more favored corridor of
   tornado potential could develop where low level shear increases with
   eastward extent closer to the warm front. Here, surface winds are
   more backed and ESRH is greater around 200-300 m2/s2.
